MACHINE FOR PEGGING BOOTS AND SHOES.

Specication forming part of Letters Patent No. 10,427, dated January 17,1854; Reissued Jul;Vr 4,

To all whom t may concern.' v

Be it known that I, JOHN JAMES GREEN- oUGH, of New York, in the countyof New York and State of New York, have invented a certain new anduseful Machine for Pegn ging Shoes and other Similar Articles, and thatthe following is a full, clear, and exact description of the principleor character which distinguishes it from all other things before knownand of the usual manner of making, modifying, and using the same.

Figure l, is a perspective view of the machine. Fig. 2, is a verticalsection; Fig. 3, plan of underside of the platform; Figs. 4, 5, 6,sections of wire pegger; Fig. 7, carriage with top piece removed; Fig.8, sec-tion of tube and shaft to move and guide the carriage; Figs. 9,l0, and 11, sections of wood pegger; Fig. 12, section of lateralmovement awl and pegger; Fig. 13, sect-ion of apparatus for cuttingmetal pegs.

Like letters refer tothe same parts in all the figures. v

My invention consists of certain parts, hereafter described in detail,which are for the purpose of forming and driving pegsof wood or metalinto the soles of shoes, boots, &c., or other similar manufactures, andin moving the work up to the pegging apparatus.

The construction is as follows: The basis, or frame of this machine maybe of any convenient form, one of which adopted by me, consists of aplane table, (05,) on legs, made of cast iron, say ten inches square,more or less. About the center of this table (ta) on the rear side,there is a standard of iron (5,) either firmly bolted to the table (05,)or made to slide in ways thereon, as hereafter described, and extendingup and curving over toward t-he front. Its upper end is divided into twoparts, in which are the bearings of a shaft, (la) by which the parts aremoved. An arm (0,) projects from the standard below the divided partabove named, whichl supports the ways of the sliding stock of the pegdriver. They shaft to which the driving cam is affixed, is in Va rightline over the stock in the plane of its motion, whether it beperpendicular over the article to be pegged, or at an angle, as shown inthe drawings, the purpose of which angle is to drive the pegs inclinedinward all the way around the shoe. This stocky (d,) is an oblong pieceof metal; having a lthinv sheet metal, its breadth and depth be i ingabout equalto the: cross section of the wooden peg, so that a strip lofwood (nl), out

of which the pegs are formed, will readily slide through it. This troughhas two rightangles to it, on the inner end, by which it is attached tothe steel block (-0,) or it may be fastened in any other convenient way.This block is an oblong piece of steel, secured by screws to the arm(0,), of the stationary standard (Z9). vIn its face there is a groove(0) cut opposite the open- .flanches (fm-Q) bent outwardon either sideat 'f ing of the trough, of sufiicient breadth and depth to receive apeg; and beside it, at the distance the pegs are tobe apart, there is asimilar groove (0) for the pegging awl to play in, which is parallel toit. Onk the opposite side of the peg groove (0,) there is still anothergroove (03,), made at an angle of about thirty degrees, to the peggroove, inclining offat the top, as clearly shown in the drawing. Thesurface between this inclined groove and the peg groove is reduced thethickness ofthe knifel (29,) the back of which is at the same angle withtheJ edge that the groove (03,) is. This thick back plays in groove(03,), and as it works up and down, forces the edge of theV knife acrossthe groove (0,) in its descent, byr Vwhich the peg is cut off its wholelength Vbyr ashaving stroke, without splitting out-'anof this ypart oflthe machine is as follows:

As the stock rises, a small projection there-` on at (r,) strikes thebentlever (5,), which is connected .with and moves forward a slidesurrounding the tube containing the 'the next peg.

peg wood. rrrwo fingers or clamps attached to the slide (t,), enterslots in the sides of the tubes, so that when the slide moves forward,the wood is fed in. In returning they slide over the peg wood. It isobvious any other device for feeding may be substituted. When the pegwood is fed into the groove (o), the knife is driven forward, and cutsoif a peg in the groove, and the piston (16,). att-ached to the stock,and working up and downu in theV groove (o,) thrusts lthe peg down intothe shoe sole below, while at the same time 'the awl (21,) makes a holefor the succeeding peg. The awl and piston are then drawnV upward,succeeded by the knife, and a second peg is fed in, and so on till thework is completed. Vhen metal pegs are to be used instead of woodenones, they may be similarly cut and used from a flat strip, with thisdifference, that instead of the angular shaving motion with a thinknife, there is attached to oneside of the trough, (y2,) that containsthe metal strip a stout piece of steel (m2) Fig.l3,which' with thestationary grooved piece forms a. shear. The cutter and trough are movedlaterally by the toggle joint (22,), worked by a rod (23,) connectingwith the eccentric.

Sometimes I use awire drawn to the fig ure the peg is to be, and thendispensing with the trough and piston, I convey the end of the wireafter passing an ordinary straightening apparatus, down through a` holein the stock, at (w,) Figs. 1, 5, and 6, .where there is a cuttingnipper (an) attached to the stock, one jaw only of whichv is movable.The shank extends up to the eccentric, and the fulcrum is at (y). The

upper end of the shank being forced outv farther forward by the shape ofthe cam (7c,) and the peg is cut off. The form of the cutters, shown atFig. 6, sharpens the end to be driven first into a chisel form. Thecutters are then freed from the wire by a spring or otherwise, and riseabove the end of it far enough to again seize it for It is obvious thattheprecise mechanisms here described to produce the effect, may haveothers substituted, which would be equivalent to those described, butthese I believe to be as simple as any, and of easy construction.

That portion of the machine which brings the work up to the properposition to receive the peg, is constructed as follows: A hole is madethroughthe table (an) in front of the standard (6,) through which passesa 'hollow cylindrical mandrel (a,) on the to-pof which there is acircular disk that receives a plate (052,) that slides from side to sideupon it; and upon this vplate (a2,) there is another oblong slide plate(a3,) that has a sliding motion at right angles to the plate (m2,). Thisconstruction enables the top plate to be moved horizontally in anydirection and revolved around. The lower end of the mandrel rests on theend of the short arm of a stout lever (b) below the end of the mandrel,this end being semispherical to allow a steady support in any position.The long arm of the lever, (b,)

is weighted, to bear up the universal 'movement carriage, as Idenominate this part of the structure, so that it has an up and downmotion required in the process. On the upper plate of the universalcarriage are proper fastenings for the boot, shoe, or other article; andon its under side there is a groove cut in the form the line of pegs areto be driven, within the groove there is a row of cogs, following thecourse of the groove, as clearly represented in Fig. 3. A

shaft (c,) extends up through the "hollow mandrel, and its upper endenters the groove. Upon this shaft, (c,) there `is a pinion, the teethof which gear into the cogs upon the plate, so that by turning thepinion, the shaft will be made to travel along the groove, or the grooveover the shaft. At the heel curve at (02,), there is an opening, so asto slide off the upper plate readily. A tube, (e,) surrounds `the shaft,(CQ) and extends from the lever (b,) (to which it is affixed so that itcannot turn) up to the under side of the pinion; there a guide pin (2,)branches ofi', and :projects up outside of the pinions into the groovein the plate above named. This keeps two points of the groove always inthe same relat-ive position in relation to the stationary parts of themachine, and causes the mandrel to revolve when the groove curves; Isometimes make a flanch on the lower end of this tube, so that themandrel bears on it instead of the end of the lever. The shaft, (c,)projects below the lever (0,) in which latter there is an oblonghole forthe purpose of giving the parts freej dom to perform their offices. Onthis lower end of the shaft, (0,) there is a ratchet wheel, with pawland clutch attached `to a horizontal lever (c,), by which the shaft andpinion are worked in one direction, at

Vplaced horizontally under the platform or table (a), to which areaflixed two arms at right angles to each other; the vertical arm isconnected by a rod 43) with the lever, while the other arm is connectedeither with the pegging stock or the eccentric, so that when the stockrises the article will be fed forward by the motion given to the leverand pinion, as above shown, and when the stock descends to drive a peg,the article will be at rest.

A modification of this feed apparatus is, to have no pinion or apparatusof ratchet, lever, or their connections; but instead thereof, to havethe guiding groove simply with the two following-pins, to keep the workin the right direction. Then instead of a simple up and down motion ofthe pegging stock, I propose to divide the pegging stock in two parts,or by moving its Ways laterally7 to give it a motion inthe directionsidewise every time it drives the pegging awl in. This device is shownin one form in Fig. l2, the lower part of the pegging stock is dividedfrom the upper part, so as to slide laterally. The operation is asfollows: l/Vhen the stock has descended and driven home the peg and thepegging awl at the same time, as before described, a side lever (m4,)extending up beside the stock, and having its fulcrum in the Stationaryframe at (m5,) has its upper end struck by a side cam (ya) on theeccentric, which causes it to force the pegging awl sidewise while inthe work, and thuscarries the work along with it, sidewise, the breadthre* quired bet-Ween the pegs; on rising, the stock slides back to itsplace again.

The standard (29,) is so attached to the bench that it can be made toslide in a right line to or from the center of revolution of theuniversal movement carriage, guided by a screw (i) (see Fig. 2), so asyto peg with two rows, or vary the sizeof the shoe to be pegged.

Having thus fully described my invention,

and some of the most import-ant modifications thereof, what IA claimtherein as new, and to secure by Letters Patent, is-

l. Cutting the peg from the peg blank by a lateral motion of the cutteragainst the side of the blank, the cutter assisting to 'v [FIRST PRINTED1913.]

hold the blank in position while it is driven, substantially as hereindescribed.

2. I also claim the combination of parts,

ticle in the course indicated by the' groove or other devicesubstantially the same, for the purpose of keeping the line of the pegscoincident with that of the awl and peg driver.

.4. I also claim so constructing yarranging and operating the shoecarriage that each point of t-he solevwhich is to receive a peg, shallbe brought successively to the samel point under the stationary peggingstandard so that the pegging shall be effected automatically andwit-hout interruption entirely around t-he shoe or other `articlesubstantially as herein described.

` 5.k I also claim in combination with the movable carriage,` thestationary pegging` standard made adjustable so that it can be set atany required distance from the center of motion of the carriage holdingthe material to be pegged as above set forth so that a second row ofpegs may be driven within or without the first row-with the samepattern-as described.

`I also claim driving the pegs by a tool having a posit-ivey motion asdescribedy in both y directions.

I wish it distinctly understood that I do Ynot intend bythe above claimsto secure ork have granted to myself, any device orcombinationzcontained, either'explicitly or substantially, in LettersPatent. granted to Joel Robinson dated October 31st, 1848, or in thespecications, drawings or model upon which'said patent was granted. f
